Optically stimulated luminescence osl dating
Later excavations in the 1980s established Malakunanja as the oldest dated site in Australia.
The first signs of Human occupation appear 2.6 m below the surface.
Many Christians have been led to distrust radiometric dating and are completely unaware of the great number of laboratory measurements that have shown these methods to be consistent.
Many are also unaware that Bible-believing Christians are among those actively involved in radiometric dating.
This soil has a characteristic called vertical cleavage which makes it easily excavated to form cave dwellings, a popular method of making human habitations in some parts of China. In several areas of the world, loess ridges have formed that are aligned with the prevailing winds during the last glacial maximum.
The word loess, with connotations of origin by wind-deposited accumulation, came into English from German Löss ( Loess is homogeneous, porous, friable, pale yellow or buff, slightly coherent, typically non-stratified and often calcareous.Only recently (2012), we have seen the chronology of Paleolithic art and culture changed completely by Uranium/Thorium dating tests on the cave art of El Castillo and Altamira.In addition, it seems likely that Aboriginal rock art in Australia will also - in the not too distant future - be discovered to be much older than presently thought.The sand below this layer was devoid of any signs of human activity.From a depth of 2.5-2.3 m there was dense occupation, from between 52,000 7,000/-11,000 BP and 45,000 6,000/-9,000 BP.
